PURPOSE

Whole body spectrometer “Sich-AKP” is designed for measurement of inhalation constituent on internal whole body emission and can be used as means for individual staff monitoring.

 

Whole body spectrometers «SICh-AKP» available in four versions, depend on tasks of the End User:

  •   «SICh-AKP»-1
  •  «SICh-AKP»-2
  •  «SICh-AKP»-3
  •  «SICh-AKP»-T

COMPOSITION

 

Base set: 

  • An arm-chair with shielding.
  • NaJ (TI) detection units.
  • Lead shielding for the detectors.
  • Supply and detector signal registration gear.
  • Personal IBM-compatible computer with printer.
  • “AKWin” software.
  • Control sample.

Additionally can be supplied :

  • CsI+NaJ (TI) detection units.
  • Information system of database operation.
  • Detectors of different geometries.
